You put the rabbit in the hat when you declare, as if it's self-evident, that abortion of a non-viable fetus is "murder". It's not.
I understand your moral objection to abortion. I share that objection. But I am not prepared to use the government to force my moral views on others. You are.
I am completely prepared to use the government to force my moral views on to others. I believe that humans should not kill other humans, and I expect the government to force that moral view on everyone else.
I believe humans should not steal from other humans, and I want the government to force that moral view onto others.
I believe humans should not assault other humans, and I want the government to force that moral view onto others.
I believe slavery is wrong (both a form of theft and a form of assault) and I want the government to force that view on others, even if they disagree with me.
Yeah, I'm all up for government forcing morality on people, because that is exactly what government is supposed to do.
If you don't believe in using the government to force your morality on other people, step aside and do not object when I use the government to force my morality onto other people. If you object, you are trying to use the government to force *YOUR* morality onto me, and you don't believe in that, remember?
